Application filed December 5, 1910. Serial No. 595,608.

To all whom it may concern:

Be it known that I, Axial, JormsoN, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Combined Can-Body Flanging and Double-Scanning Machines, of which the following is a specification.

My invention relates to improvements in can body flanging and double seaming machines.

The object of my invention is to provide an automatic machine of a simple, efficient and durable construction, by means of which the ends of can bodies may be flanged, the can heads automatically fed and assembled with the flanged can bodies and double seamed thereon, and hermetically tight seams formed with certainty and uniformity, and which will be adapted for use in canning factories for closing filled cans by double seaming the final heads or covers thereto.

The machine embodying my invention comprises in coiiperative combination, a pair of rotary carriers, each furnished with a plurality of segmental flanging dies adapted to register together as the carriers ro tale, a plurality of reciprocating Hanging -dies mounted on one of the carriers, a can head holder nd can head feeder adapted to automatic lly feed or deliver the can heads or covers one by one to the flanged can bodies as they are movedtoward the can head feed mechanism, the can head feeder being released by the action of the propelled can, and a further rotary carrier furnished with a plurality of pairs of can holder chucks and a plurality of double seaming heads, each furnished with a set of double seaming rollers or tools, and to which last mentioned carrier the flanged can bodies with the can heads thereon are delivered by the carrier to which the can heads are delivered, the same being the intermediate one of the three carriers.

My invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described and more particularly specified in the claims.

In the accompanying drawings forming a part of this specification, Figure 1 is a central, vertical, longitudinal section of a combined can body flanging and double seaming machine embodying my invention, partly in elevation. Fig. 2 is a plan view looking from the broken lines 2-2. of Fig.

Fig. 15 is a central, vertical section of one of the dou le seaming heads. Fig. 16 is a detail sectional elevation of the flanging dies on a larger scale than that disclosed by Fig. 1 of the drawings. Figs. 17, 18 and 19 are detail part sectional views illustrating the steps carried out in the double seaming of the head or cover to the filled can. Fig. 20 is a broken detail elevation, partly in section, of the can head or cover holder and the feed slide working therein,

illustrating'the feed slide as cutting out one of the can covers from the stack of held covers.

eferring more particularly to Figs. 1 and 2 of the drawings, 1 represents the frame of the machine, the same being of any suitable form or construction adapted to give support to the other parts. 2 is an intermittently rotating carrier furnished with a plurality of segmental, external flanging dies 3, each adapted to partially embrace the'end of the can body, and with a plurality of can holders 4, each preferably individually adjustable by means of a separate adjusting screw 5 mounted in a depending bracket or arm 6 of the carrier 2. The fianging die carrier 2 is also furnished with a plurality of reciprocating circular or internal flanging dies 7, each secured to a 2 stem 8 extended through a suitable guide projecting from the bracket 10 secured to the carrier 2, and to cotiperate with the segmental fianging die 3 on the carrier in forming the flange 11 on the can body 12, and also with the cooperating segmental external fianging die 13 on the intermediate rotary carrier 14, Figs. 1 and 16 of the drawings. Each of the flanging dies 7 is reciprocated as required, preferably by means of a lever 3Q 15, fulcrumed at 16 to the bracket 10, and operated by a .movable cam 17 surrounding the upright shaft 18 of the carrier 2 through the connecting link 19., which is furnished with an anti-friction roller 20 for engagement with the cam 17, Figs. 1, 2 and 3 of the drawings. The intermediate flanging die carrier 14 rotates intermittently in unison with the fianging die carrier 2, and is furnished with a plurality of flanging dies 13, preferably four in number, so that a quarter turn of the carriers 2 and 14 brings a pair of the segmental flanging dies 3 and- 13 into register with each other so that they completely surround and embrace the upper end of the can body and coact with the reciprocating fianging dies 7 to form a flange upon the upper end of the can body, Figs. 1 and 16 of the drawings. Each of the segmental flanging dies 13 on the rotary carrier 14 is furnished'withan upward segmental extension 21 having a segmental groove or shoulder 22 to serve as a seat to receive and temporarily support the can head or cover when the same is fed to the carrier 14 by the can head feeder 23 from the can head holder 24, Figs. 2 and 4 of the drawings, which fianging die coiiperates with the segmental guide wall 25 for holding the flanged can in proper position as propelled over the segmental can support 25 by the rotary carrier 14 beneath the can head feed mechanism and toward the seaming mechanism for securing the loosely applied head thereto, Figs. 2and 4 of the drawings.

The intermittently rotating seaming head carrier upon which the rotary seaming heads and upper and lower can holder chucks are mounted, preferably consists for convenienceof construction of two separate members, an upper one 26 upon which the rotary seaming heads 28 and upper can holder chucks 29 are mounted, and a lower one 27 upon which the lower can holder chucks 30 are mounted, both members 26 and 27 of the carrier being secured to the same upright hollow shaft or sleeve 31, Figs. 1, 6, 7, 8, 10, 11, 12 and 13 of the drawings. The carrier 26 is intermittently rotated in unison with the carriers 2 and 14 and is preferably furnished with four pairs. of can holder chucks 29, 30, one chuck of each pair being mounted to reciprocate to and from the other to clamp and unclamp the can body and can head between them. The lower chuck 30 of each pair is preferably the reciprocating one and is preferably moved up and down as required to clamp and unclamp the can and to hold the same stationary during the double seaming operation by means of a stationary cam 32 on the frame of the machine through the bent lever 33, having roller 34 for engagement with the cam and toggle-acting connecting link 35 which is pivoted at its upper end to a block 36 carried by the lower chuck 30, a spring 37 being interposed to give the chuck a yielding clamping action against the can and to accommodate for slight variations in the length of the can bodies, Figs. 1, 6, 7 and 8 of the drawings. The seaminghead carrier 26 is furnished with four rotaryseaming heads 28, one for each qair of can holder chucks 29, 30; Figs. 1 and 2 of the drawings, andeach rotary seaming head is furnished with a'set of double seaming rollers, Figs. 10, 12 and 15 of the drawings, each set of 'doubleseaming rollers preferably consisting of a seam forming roller 38 and a seam closing roller 39.

Each of the rotary seaming heads 28 is secured to and carried by a hollow shaft 40, and is provided with radial slides 41 upon which the seaming rollers 38 or 39 are directly journaled, each of the slides 41 having an adjustingmember 42 secured thereto by an adjusting screw 43 and clamp screw 44.

Each of the seaming roller slides 41 is moved in and out to operate the seaming rollers by means of a seaming roller lever 45, fulcrumed by a pin 46 on the seaming roller head 28 and furnished with an antifriction roller .47 for engagement with the cam 48 or 49 on the cam sleeve 50 which surrounds the hollow sleeve or hub 51 of the seaming head, Figs. 12 and 15 of the drawings. Each of the cam sleeves 50 is reciprocated as required to successively 0perate-the seaming rollers 38, 39 by means of an arm 52, having a fork or yoke 53 engaging the cam sleeve 50, said arm 52 being secured to a vertically sliding rod 54 mounted in suitable guides 55 on the carrier 26, Figs. 1, 10, 11 and 12 of the drawings. The sliding rod 541 is reciprocated as required to accommodate the cam sleeve by means of a stationary cam 56 on the frame of the machine which engages an anti-friction roller 57 on the lower end of said rod 54, Fig. 1 of the drawings.

Each of the rotary seaming heads 28 is axially rotated as required for operating the seaming rollers carried thereby by means of a spur gear 58 on the seaming head shaft 40 which meshes with a spur gear 59 on the upright shaft (30, which fits within the upright hollow shaft 31 of the rotary carrier 26, said shaft (30 having at its lower end a bevel gear 61 which meshes with a bevel gear (32 on the main driving shaft 63. Figs. 1, 2 and 3 of the drawings.

The required intermittently rotary movement is preferably imparted to the three rotary carriers, 26, 1+1 and 2 from the main driving shaft (53 by a Geneva stop movement, Figs. 1, 3 and 5 of the drawings, the pins (34: of which carrying the rollers 5 are on the upper face of the bevel gear 61, and the radial slots 66 of which are on wheel ()7 on an upright countershaft (58 which carries a spur gear 69 which meshes with a spur gear 70 on the shaft 71 of the intermediate carrier 14. The shaft 71 has a spur gear 72 which meshes with a spur gear 7?) on the hollow shaft 31 of the rotary carrier member 26, and also with a spur gear 74 on the shaft 18 of the rotary carrier 2, thus rotating the adjacent carriers in opposite directions as required.

Each of the upper non-rotary can holder chucks 29 is removably secured by screw threads to a two-part hollow stem or sleeve 75, 76 which is secured to a bracket or arm 77 on the rotary carrier 26, Figs. 1 and 15 of the drawings. Inside the hollow stem 75, 76 a movable knockout or ejector rod 78 is preferably provided, the upper end of which during the rotary travel of the carrier 26 moving beneath the downwardly iiicline cam plate 7 8 is forced down to free or eject the can head after it is seamed to the can body from the upper can holder chuck 29, to prevent the headed can from sticking thereto. The upper can holder chuck 29 is preferably furnished with a removable chuck plate or ring 79 secured thereto by screws 80 so that it may be readily removed and replaced when desired, Fig. 15 of the drawings.

Each of the seaming roller slides ll, 42 is preferably furnished with a spring 81 for restoring the seaming rollers to their open or normal position after each seaming operation.

To properly throw the movable cam 17 which operates the reciprocating flanging dies 7 and thus cause each of the flangmg I l l l l I lever 90 below its fulcrum point.

dies to be properly reciprocated in unison with the segmental carrier l-lwhich carries the cooperating segmental flanging dies 13 at each stop or period of rest of the carriers 1t and 2, there is provided for said cam an operating lever 82. Fig. 3 of the drawings, which at one emlengages the said cam and is connected at its opposite end by a link .73 with a bell crank lever 84 pivoted to the frame at SS, and having an arm 86 engagmg successively the pins 87 carried and upwardly projecting from the bevel gear (31,v

one of said pins 87 being radially in line with each of the (leneva step pins 64.

The can head holder 24 preferably consists of a base ring furnished with vertical guide pins 88. forming a holder in which the can heads may be placed in a pile or stark one flat on top of another, Fig. 20 of the drawings.

The flanged cans 12 are successively removed from the can holders 4 of the carrier 2 and guided toward the can cover feed mcch: iism as propelled by theintermittently rotating carrier 14: by means of the segmental deflecting guide wall 25, which upwardly projects from a supporting shelf onto which the tlanged cans 12 are received as removed from the can holders 4 of the carrier 2, the forward end of the deflecting guide wall projecting within the path of the cans contained on the holders 4, while the supporting shelf is in horizontal alineiuent with the intermittently rotating carriers 2 and member 27 of the seaming head carrier and forms the supporting connection between these said members, Fig. 2 of the drawings. The opposite end of the guide wall 25' extends over the rotary carrier member 27 andguides the flanged cans 12 with the head loosely applied thereto as propelled over the supporting shelf 25 by the carrier 14 onto the said carrier member 27.

The can head feeder 23 preferably consists of a reciprocating blade mounted for movement in suitable guide-ways 89 in the supporting bracket 89 attached to the frame of the machine, Fig. l of the drawings, and it is preferably thrown inwardly by a filli-rumed lever 90. The upper end of said lever 90 which bears against the slide or feeder blade 23 when thrown outwardly, is

held inwardly by the pressure of a heavy compression spring 90 interposed between the frame 1 and the lower end portion of the The fulcrumed lever is actuated to throw outwardly its upper end by a series of inclined cams 91 secured to the under face of the gear 72 which cams are successively engaged by an antifriction roller 92 on the connecting link 93 working through a guide 93'. The slide blade 23, when released, as hereinafter explained, is preferably thrown outwardly by arm 94, the upper end of which engages the outer end of the slide blade 23 and serves to return the same after being forced mwardly by. the action of the lever 90, on the locking means for the slide blade being released and the upper end of the fulcrumed lever 90 being thrown outwardly by the action of the inclined cams 91 and roll 92. It will be unheavier than spring 94 to overcome the opposition ofltered thereby, as the roll 92 rides off of the inclined cams 91 during the rotation of the gear 72. The said lever 90 at its upper end bears loosely against the outer end of the slide blade 23,.when the same is at its outward position, as illustrated in Fig. 4 of the drawings. This feed slide 23 when moved inward by the throw of the lever 90, is held locked in said position by means of the locking catch 99, normally held inwardly pressed by the spring 96 and said catch engages with the notched section 97 of the feed slide 23, at one side thereof adjacent its 25 inner end, Fig. 2 of the drawings. The looking catch 96 is carried at the upper end of a rotatable stud 98, to the lower end of which is attached a cam lever 99, which lever projects within the path of a can conveyed by the carrier 14 beneath the can head feed mechanism toward the carrier 26. As the cam lever 99 is engaged by the flanged can 7 12, the said lever is forced outwardly, turning the stud 98 to release the held feed slide 23, which is withdrawn from beneath the body of held can heads or covers 12 by the action of the spring 94, allowing the entire stack to lower the depth of one can head or cover, which loosely applies the lower'most one of the staclnonto the flanged end of the can 12, a portion thereof resting within the segmental groove 22 of the flanging die 13 at a period or rest' at such time beneath the can head or cover feed mechanism.

" However, 'prior to the removal of the flanged can with its loosely applied head or cover, the feed slide 23 will have been forced inward its full distance by the action of the lever 90, operated through the medium of the roll 92 working against the cam 91. As thus forced inwardly the feed slide 28 is moved between the lowermost two heads 12 of the stack, Fig. 20 of the drawings, cutting out, so to speak, the lowermost head or cover 5 and sustaining or supporting the remainder of the stack, the said feed slide or blade as thus moved inwardly being held locked in such position by the spring held locking catch moving into engagement with the notched section 97 thereof, in which position it is held until the cam lever 99 is thrown by the next flanged can moved toward the can head feed mechanism. It. will thus be noted that can heads are only re leased by the action of a flanged can, conderstood that the spring 90 is sufllciently sequently the heads are only supplied on a flanged can being positioned to receive the same. The seamed cans are discharged from the carrier 26 by means of the deflecting wall extension 92 of the discharge runway 93', which wall extension lies within the path of the seamed can to remove the same from the chucks 30 and directs the said can into the discharge runway-93, Fig. 2 of the drawings. During the approach of the seamed can toward the discharge runway, the roll 34 of the can holding chuck 30 moves beneath the downwardly inclined cam plate 94 Fig. 8 of the drawings, and gradually draws downward the said holding chuck from its raised position, to place the seamed can supported thereon in line with the discharge runway 93 the roll 34 entering beneath the cam plate 94 at approximately the 'same time as the upper projecting end of the ejector rod'78 moves beneath the inclined cam plate 78.

Referring to Figs. 2 and 5 of the drawings, it will be noted that the surface of the intermediate carrier 14 is cut away at a down ward incline adjacent each of the flanging dies 13, to form a supporting seat 95 onto which the can heads 12 are deposited from the can head feed mechanism, and which seats during the movement of the carrier gradually guide the same into the upper end of the flanging dies and onto the flanged end of the can as it is brought into vertical alinei nent with the can head holder 24. By this means the can heads are gradually lowered .onto the flanged end of the can 12, and prevent-c d from suddenly dropping thereon. In fact, the seats 95 may be said to constitute a curved outward inclined extension ofthe segmental groove 22 or" the flanging dies 13.

The operation of the apparatus may be briefly described as follows, motion being imparted to the drive means for actuating the connected intermittently rotating carriers and their associated working parts.

The cans tov be flanged and have heads applied thereto are delivered, in any-suitable manner onto the can holders 4 of the rotating carrier 2 and are conveyed thereby by an intermittent rotation toward the carrier 14 until the segmental flanging die 3 is in registry with the segmental flanging die 13 of the carrier 14, when the two carriers are brought to rest for a short period. During the interval of rest, the reciprocating flanging die 7 'is lowered, to turn down the projecting end of the held can or can body 12 onto the segmental flanging dies 3 and 13 to form the circumferential flange 11. The flanging die 7 is then raised from within the segmental dies of the rotary carriers 2 and 14, and rotation imparted to said dies, the rotary travel of which carriers carry forwardly the flanged can body 12 until the same bears against the right hand projecting end of the curved deflecting wall 25, ar-' 99,2lying within the path of its movement,

releasing the locking catch 96, when the feed-blade .23 moves outwardly and permits the stack-of retained can covers or heads to lower the depth of a single cover. The feed blade is then forced inwardly by the ac- 30 tion of the lever 90 to cut out the lowermostcanhead of the stack of heads, leaving the same resting properly positioned on the flanged end of the can. The can with its loosely applied cover is thenadvanced toward the intermittently rotating carrier 26, until the said can is guided by the wall 25 onto one of the lower can holding chucks of the said carrier 26, gradually moving from within the s here of the seg 30 mental flanging die 13 o the rotary carrierlt. .During the rotary travel of the carrier 26, the can holding chuck 30 is I gradually :raised to place the flanged can with its loosely applied head against the '35 upper-can holding chuck 29 and within the sphere of the-seaming heads 28, when the doubleseaming rolls 38 and 39 successively act againstthe flangeof the can head and of the held can to double seam the flange ofone onto the other, after which the can holding chuck 30 is gradually lowered by the engagement of the roll 34 with the downwardly inclined cam plate.9-it' and the ejector rod 78 forced downward by its en- 'gagementwith the cam plate 78 to force thedouble seamed can from within the seam-' v pairsofupper and lower can holder chucks anda plurality of rotary seaming heads furnished with seaming rollers, of an intermittent-1y rotating carrier having a plurality of segmental external flanging dies, an in- 35 termediate rotatingcarrier having a plurality of segmental external flanging dies,
